We don't know how your text file looks like... We dont't know how you are punching in the numbers... So show us...

If the text file has the numbers line by line, try this...
Code:
sort input.txt | head -1

--ahamed

in my text file is:
Code:
22
3
5
2
1

Then this should work...
Code:
sort input.txt | head -1

In case of numerical sort, "-n" option must be used.

Code:
$ sort -n ff
1
2
3
5
22
$ sort  ff
1
2
22
3
5
$
